Study Notes
Understanding Physical Changes
- Refers to alterations in the body that do not change chemical composition, such as growth in height or changes in body shape.
- Includes modifications in skin texture, hair growth, and increase in body mass.
Stages of Prominent Physical Changes
- Most significant during puberty, which typically occurs between ages 9 to 14 for females and 10 to 15 for males.
- Associated with hormonal changes that trigger growth spurts and development of secondary sexual characteristics.
Influential Factors in Physical Changes
- Least likely to be influenced by external environment or social factors; genetics plays a predominant role.
- Individual differences stem from hereditary information, rather than lifestyle choices or socio-economic status.
Common Physical Changes from Childhood to Adulthood
- Growth spurts leading to increased height and muscle mass are commonly observed.
- Development of secondary sexual characteristics, such as breast development in females and voice deepening in males.
Focus of Studying Physical Changes
- Emphasis on understanding how physical maturation impacts individual development and psychological growth.
- Observations on how these changes affect emotional well-being, social dynamics, and self-image during transitions into adulthood.
Growth Spurt
- Height and weight increase significantly during puberty.
- Growth spurt typically occurs between ages 9-14 in girls and 10-16 in boys.
- After peak growth, growth plates in bones begin to fuse.
Development of Secondary Sexual Characteristics
-
In Girls:
- Thelarche marks the beginning of breast development.
- Hips widen in preparation for potential childbearing.
- Pubic and underarm hair begins to appear.
- Menarche, or the onset of menstruation, usually occurs around ages 12-13.
-
In Boys:
- Testicles and penis enlarge during puberty.
- Pubic, underarm, and facial hair growth initiates.
- Voice deepens due to larynx growth.
- Muscle mass and overall strength increase.
Skin Changes
- Increased oil production contributes to acne formation.
- Body odor changes result from enhanced sweat gland activity.
Body Composition Changes
-
In Girls:
- There is an increase in body fat percentage, particularly in hips and thighs.
-
In Boys:
- Decreased body fat percentage occurs alongside an increase in muscle mass.
Hormonal Changes
- Sex hormone production rises, with estrogen predominant in girls and testosterone in boys.
- Hormones regulate physical development and can impact mood and behavior.
Other Effects
- Fat distribution alters during puberty.
- Development of an adult body shape and contours becomes evident.
- Increased energy levels and shifts in sleep patterns are common.
